Went on vacation, forgot a couple things

[Scottp999]

Hi, before we left for a week, I remembered to turn off the water at the home entry point and turn off power to both water heaters. I forgot to turn off power to a water softener and another anion exchange unit plus a 12gpm UV, and 1gpm UV lamps. How concerned should I be about that? For example the anion exchange unit has a max 28 days to regen and I have no idea how close that was , would it be damaged if no supply water? Thanks in advance.
